Mia is calculating the volume of the cylinder below using the following work.

A cylinder with height of 47 meters and diameter of 35 meters.

She confused the height and the diameter.
She forgot to include pi as a factor in the volume expression.
She applied the exponent before multiplying 17.5 and 47.
She squared 17.5 instead of 35.

What was Mia’s first error?

She forgot to include pi as a factor in the volume expression.

Step-by-step explanation:

the formula is

V= (pi) r^2 h

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
